2024-08-23spl: Create a function to init spl_load_infoSimon Glass
Rather than having every caller set this up individually, create a common init function. This allows new fields to be added without the risk of them being left uninited. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Michael Trimarchi <michael@amarulasolutions.com>
2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2023-11-16spl: Convert semihosting to spl_loadSean Anderson
This converts the semihosting load method to use spl_load. As a result, it also adds support for LOAD_FIT_FULL and IMX images. Signed-off-by: Sean Anderson <seanga2@gmail.com>
2023-11-16spl: Only support bl_len when we have toSean Anderson
Aligning addresses and sizes causes overhead which is unnecessary when we are not loading from block devices. Remove bl_len when it is not needed. For example, on iot2050 we save 144 bytes with this patch (once the rest of this series is applied): add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-144 (-144) Function old new delta spl_load_simple_fit 920 904 -16 load_simple_fit 496 444 -52 spl_spi_load_image 384 308 -76 Total: Before=87431, After=87287, chg -0.16% We use panic() instead of BUILD_BUG_ON in spl_set_bl_len because we still need to be able to compile it for things like mmc_load_image_raw_sector, even if that function will not be used.

2023-11-16spl: Remove filename from spl_load_infoSean Anderson
For filesystems, filename serves the same purpose as priv. However, spl_load_fit_image also uses it to determine whether to use a DMA-aligned buffer. This is beneficial for FAT, which uses a bounce-buffer if the destination is not DMA-aligned. However, this is unnecessary now that filesystems set bl_len to ARCH_DMA_MINALIGN instead. With this done, we can remove filename entirely. Signed-off-by: Sean Anderson <seanga2@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2023-11-16spl: semihosting: Don't close fd before spl_load_simple_fitSean Anderson
On real hardware, semihosting calls tend to have a large constant overhead (on the order of tens of milliseconds). Reduce the number of calls by one by reusing the existing fd in smh_fit_read, and closing it at the end of spl_smh_load_image.

2022-09-29treewide: Drop image_header_t typedefSimon Glass
This is not needed and we should avoid typedefs. Use the struct instead and rename it to indicate that it really is a legacy struct. Signed-off-by: Simon Glass <sjg@chromium.org>
2022-04-01spl: Add semihosting boot methodSean Anderson
This adds a boot method for loading the next stage from the host. It is mostly modeled off of spl_load_image_ext. I am not really sure why/how spl_load_image_fat uses three different methods to load the image, but the simple case seems to work OK for now. To control the presence of this boot method, we add a config symbol. While we're at it, we update the original semihosting config symbol. I think semihosting has some advantages of other forms of JTAG boot. Common other ways to boot from JTAG include: - Implementing DDR initialization through JTAG (typically with dozens of lines of TCL) and then loading U-Boot. The DDR initialization typically uses hard-coded register writes, and is not easily adapted to different boards. BOOT_DEVICE_SMH allows booting with SPL, leveraging U-Boot's existing DDR initialization code. This is the method used by NXP's CodeWarrior IDE on Layerscape processors (see AN12270). - Loading a bootloader into SDRAM, waiting for it to initialize DDR, and then loading U-Boot. This is tricky, because the debugger must stop the boot after the bootloader has completed its work. Trying to load U-Boot too early can cause failure to boot. This is the method used by Xilinx with its Zynq(MP) processors. - Loading SPL with BOOT_DEVICE_RAM and breaking before SPL loads the image to load U-Boot at the appropriate place. This can be a bit tricky, because the load address is dependent on the header size. An elf with symbols must also be used in order to stop at the appropriate point. BOOT_DEVICE_SMH can be viewed as an extension of this process, where SPL automatically stops and tells the host where to place the image. Signed-off-by: Sean Anderson <sean.anderson@seco.com>
